node中https请求 | 实现https的请求，获取图片，然后转成base64字节码

this.checkCodeUrl = ‘https://www.test.com/kaptcha.jsp‘;var https = require(‘https‘);https.get(this.checkCodeUrl,function(res){ ???????var datas = []; ???????var size = 0; ???????res.on(‘data‘, function(data){ ???????????datas.push(data); ???????????size += data.length; ???????}) ???????res.on(‘end‘, function(data){ ???????????var buff = Buffer.concat(datas, size); ???????????var pic = buff.toString(‘base64‘); ???????????callback({success:true, data:pic}); ???????}) ???}).on(‘error‘,function(err){ ???????console.log(‘获取验证码异常,异常原因‘+err); ???????callback({success:false, msg:‘获取验证码失败‘}); ???})

var https = require(‘https‘);var iconv = require(‘iconv-lite‘);var querystring = require("querystring");var reqData = { ???????????str1:‘11‘, ???????????str2:‘22‘ ???????} ???????var postData = querystring.stringify(reqData); ???????var opts = { ???????????method:‘POST‘, ???????????host:‘www.test.com‘, ???????????port:‘443‘, ???????????path:‘/api/test‘, ???????????headers:{ ???????????????‘Content-Type‘:‘application/x-www-form-urlencoded‘, ???????????????‘Content-Length‘:postData.length ???????????} ???????} ???????var req = https.request(opts,function(res){ ???????????var datas = []; ???????????var size = 0; ???????????res.on(‘data‘,function(data){ ???????????????datas.push(data); ???????????????size += data.length; ???????????}) ???????????res.on(‘end‘, function(){ ???????????????var buff = Buffer.concat(datas, size); ???????????????var str = iconv.decode(buff,‘gbk‘); ???????????????callback({success:true, data:str}); ???????????}) ???????}) ???????req.on(‘error‘,function(err){ ???????????console.log(‘异常,异常原因‘+err); ???????????callback({success:false, msg:‘失败‘}); ???????}) ???????req.write(postData);
